101 (#153) ############################################ CARDING AND GONDENSING > the finest carding wires may be obtained. These points, however, are really too delicate for anything save cotton for which plough ground wire is largely employed By method (d) a rough back and side sharpening of the wires results, and if an emery trimming roller is employed turning from side to side during the grinding process, a useful approximation to the plough grinding of cotton cards may be obtained. As already indicated, workers and strippers are usually ground away from the card and the swifts and doffers in situ. But in the latter case what becomes of the fine wire dust !! In this chapter, although a great many points have been touched on, the subject has not been dealt with exhaustively. Perhaps no other of the textile processes so merits consideration, nor so well repays both worker and master for the time spent in the attempt to grasp intelligibly the many principles involved. The following are a few practical comments on card- ing and card-setting given by the late Mr. Auty, one of the best-known of Yorkshire manufacturers, in a lecture delivered at Leeds University. A good deal may now be read into these statements and suggestions. 1. Set feed rollers close to keep clean teeth, and run them at the same speed. 2. Card-clothing better than licker-in fillet for the licker-in, as it drops less material. The latter will drop six times as much. 3. Strippers should be speeded to just nicely beat the worker. If speeded too much, will not deliver as well to the swift, they should be kept off swift, but run near to worker. * 4. Be particular in gauging (setting) a machine both sides are alike, looking out for dark (where not stripped) and light sides. * To lay the wool softly on the swift the strippers should be speeded up.
